About This Tool
Paste messy JSON and get it formatted, validated, and syntax-highlighted instantly. Also catches errors and tells you exactly where the problem is. I use this daily because API responses never come pretty-printed.
How to Use
- 1Paste your JSON into the input area
- 2Click format to pretty-print it with proper indentation
- 3If there's an error, the exact line and character are highlighted
- 4Copy the formatted output or switch between 2-space and 4-space indentation
Why Use This?
Reading minified JSON is miserable. And hunting for a missing comma in 500 lines of unformatted data is even worse. This tool makes both problems go away in one click.
